[cairo] [PATCH v3 6/7] test: Ensure output dirs exist, falling back to current dir if needed

[Bryce W. Harrington]

This change makes several tests behave more like ps-eps.c, et al by
making them attempt to mkdir "output", and in case of trouble use "."
instead.  filenames are now allocated at runtime due to this change, so
ensure the corresponding free()'s are in place as well.

This should facilitate running the test suite with a relative path
outside cairo's source tree, such as when employing the CAIRO_REF_DIR
environment variable.
